You will have such a good opportunity there to speak from your heart to her, and have her listen with her heart. And vice versa. Without another love in the wings, I don't see how she could keep the heart closed. But in the meantime, keep that down in the dumps thing going. Make her think you have accepted defeat. And just accept everything she says. When you get there, they will give you both rules for discussing. At that point it will become fair and you can really say what you are feeling. Until then just swallow it.
